Johnson, Columbus, Ohio, assignor toj The Buckeye Steel-Castings Company Colum- Application nb emb ne, 1931, seam). 573,96 1 .i '3' Clairns, (01. 213- 57 s invention relates to improvements incenter castings and body bolsters-for railway freight cars, and more especially to a device of "this-char:- acter designed .for use with wdraft mechanism of the tandem draft gear type.

gearings are, arranged in tandem formation, this prevents the backstop used with draft mechanism fromprojecting-forwardl y to thesame ex-, ;tent.as in'the past, due tothe fact v-that some of theispacej previously occupied :by' the back :stop must be utiiizedto accommodate the rear-(draft gearing; i :The primary purpose of the. present invention is to provide a combined center casting and body bolster construction having .the necessary pocket or clearance space tocaccommodate the rear :draft I gearing, and'yet of such design as tonotimpain the strength .of the tbodybo'lste'r construction.

With the foregoing object outlined and with other objects in view which willappear asthe description proceeds, the invention consists the novel "features'hereinafter described in detail," illustrated in the accompanying drawings, and more particularly pointed out in the appended claims."

In'the drawings, i i l I Fig. 1 is a plan view of the-improvedconstrum tion, the portion awe leftbeing taken from ,the bottom, and the portion at the right being takenfrom the top and having the built-up construction omitted.

Fig.2 is a front elevation of the same, partly in'transverse vertical section, the section being taken on the'i ine 2-2of Fig. 1. 1

taken lengthwise of the car.

Figs. 4, 5 and 6 are views like of Fig. 4.

Fig. 7 is a top plan view partly in horizontal vention illustrated in Figs; l to 3"inclusive, it will be noted that the center casting 22 is integralw'ith the center plate 23 which has the usual king pin aperture 23a. t t l A web 24 which forms the main portions of the bottom of a body bolster, is made-up otfia'nges or arms which project laterally from the center Figs. '1, 2 andB, respectively, but showing a modification. u sectional portion Fig. 5is taken on the line 5- 5 plate, and in these arms, the side bearings 25 are arnangeddirectlybelow side bearing braces 26; all of theparts '22, 23, 2 4, .25 and 2 6 being portions or a one-piece metal structureor be.-

H ing integral with ,one another. Each sidebear If draft mechanism is used in which the draft (not shown), and in accordance with the present invention, the bearing plate 29 extends entirely across-thecentral portion of the casting and is arranged rearwardlylof the axis of the king Jpi-n ho1e;23a.i',';

Extending rrearwar f ll'yr-from the plate 29 are l a pair ofiside plates- 30 whiohare provided with holesto receive the rivets 31 employed in securingthe casting to the'center sills 35.

In'my .new design, the inner flanges 34 of the center :sills are cut away. at 331to accommodate the bottom tie 32 .oijthe ic'asting, and itwill be noted that this bottom Etie has a rearwardly extending l overhanging ledge 1 32 a which overlaps the cutawayportions of the flanges 34. A rib 32b is vertically arranged atthe central portion of the castingflaindextends from the tie 32 to the bearingrplate 129 for reinforcing purposes. 1 Horizontal 3 ribs 32c a'lsoextend irom the wall 29 to the side walls 30 for reinforcing purposes.

.Immediatelyforwardfofthe wall 29 the center I plate llis braced bya VerticaI rib 36, and a Fig. 3 is a vertical sectional view otthe sameg transverse flange 3 15f 9 only the bottom i bearings; their braces and the'central portion of the body bolster 28 are formed of the one-piece metal casting, and the remainder of the body bolster is preferably made or built-11p metal parts,= which are spliced to the casting by the usual pressed plate construction '38s i i The construction illustrated in Figs. 4 to 6 inclusive differs from that shown inFigs. 1, 2 and 3 .in that'the center casting" 22a: is made separate from the portion which forms the cross part of the bolster, so-that the inturned flanges 34x of the center sills 352: may extend forward beyond the axis of the king pin hole as indicated at 3|:c in Fig.4. It will be noted that the center castis not cast withIthe center plate 23.- In this case, the rib 36m and flange 311:, as well as the re'mi orcing ribs at. the rear of the plate 29a: are

ing has an integral plate '32:: which, however,

cast integral with the center casting 22m. The general details of the center plate 231', arms 24:0, side bearings 25m and said bearing braces 26:11, all of which are cast integral, are the same as the construction illustrated in Figs. 1 to 3 inclusive.

The embodiment illustrated in Figs. 7 to 9 inclusive differs from that shown in Figs. 1 to 3 inclusive in that the flanges or arms 24c are relatively short and terminate just beyond the center sills c. They are spliced to the usual pressed plate construction 5386 between the center plate 23c and the side bearings (not shown). Of course, in this instance, the side bearingsand their braces would be separate castings:

It is apparent that the invention may be modified for accomplishing the same result, without departing from the spirit of the invention, as

expressed in the claims.

What is claimed and desired to be secured by" Letters Patent is:
